The invention relates to a base of an electric hydraulic lifting jack. The base is of a plate structure and is provided with bolt holes, oil conveying holes and plugging holes. The bolt holes are matched with bolts to fix a lifting cylinder, an oil pump body, an oil box and other lifting jack structures. Each oil conveying hole is a round hole in the base of the lifting jack and serves as an oil path for hydraulic oil to communicate the oil pump body on the base with the lifting cylinder and the oil box. Each plugging hole is a round hole which communicates the outer end of the corresponding oil conveying hole with the lateral surface of the base of the lifting jack and is provided with an inner thread, the diameter of the corresponding plugging hole is larger than that of the corresponding oil conveying hole, and a sealing plug or a connecting oil pipe can be installed in the corresponding plugging hole. The base of the electric hydraulic lifting jack is simple and reasonable in structure and enables the oil pump body installed on the base to be communicated with the lifting cylinder and the oil box, and the connecting oil pipe is eliminated, so that the electric hydraulic lifting jack is more compact in structure and convenient to use and portable. The base is suitable for a small electric hydraulic lifting jack.
